ARTIFICIAL BATHING POOL.

Application filed'December 18, 1926. Serial No. 155,732.

This invention has general reference to artificial bathing pools or swimming tanks, and has more particular reference to such pools or tanks to which movement is imparted by meclmnical means, so that the water is con stantly in motion, and the att 'activeness and enjoyment of bathing is consequently enhanccd.

l n a co-pending application, Serial No. 150,108, filed November 22, 1926, I have shown, described and claimed a rectangular bathing pool to which longitudinal rocking movement is imparted for the purpose of simulating surf by causing the water in the pool to be projected in the form of waves alternately toward the respective ends of the pool and such waves to break against said ends.

A primary object of my present invention is to improve upon the bathing pool disclosed in the co-pending application aforesaid, by providing a circular form of pool in which the movement imparted to the water is not confined substantially to lines parallel with the longitudinal axis of the pool, but a con siderable portion at least of such movement is along curved lines.

A further object is to produce simple, effective and eilicient meansfor imparting the desired movement to the pool.

Another object is to provide means for die livering fresh or treated water to the tool, preferably in the form of a shower or spray, and means for maintaining a predetermined level of the water in the pool.

And a still further object is to support the pool in such manner that side thrusts, shocks and wear upon the moving mechanism will be minimized.

The means by which the forgeoing and other objects are accomplished by my invention, and the manner of their accomplishment, readily will be understood from the following description on reference to the accompanying drawings, which. depict preferred embodiments of the invention, and in which z-.-

The single figure is a transverse sectional side elevation of one arrangement of a circular pool and associated parts, the section being taken substantially on the center line of the pool.

As shown in the drawing, the bottom 5 of the pool is supported upon trusses 6, the number of which will vary with different dimensions of the pool, and said trusses also support the side 7, which has a vertically-concave inner surface throughout its length. An annular bearing-plate (5 is secured to the under side of the trusses 6 near the outer ends .9. Arranged centrally of the tank is a shaft- 10, which terminates at its lower end in a ball 11, mounted for universal pivotal movement in a socket bearing provided therefor in a base 12 which serves as a rocker surface for the trusses that support the bottom and side of the pool. At its upper end shaft terminates in a ball 13, mounted for universal pivotal movement in a socket bearing carried at the end of an arm 14, which is fast upon a vertical shaft 15 that is driven from a motor 16, through a pinion 17 a spur gear 18, a worm 19 and a Worm-gear 20. A pipe 21. supplies fresh or treated water to the pool through a perforated spraypipe 22, and a plpe 23, passing through the bottom of the pool near its center, has its open upper end substantially at the level desired to be maintained for the water in the tank, while at its lower end said pipe discharges into a drain 24.

Due to the manner in which the pool is supported, and. the arrangement of the means employed for moving it, a substantially helical movement is imparted to the pool. The water moving from the rising end of the helieally-nioved pool toward its lowering end, first passes through the perforations in the lower portion of plate 8 and into the space between said plate and the concave inner surface of the side 7, and as the movement of water toward the lowering end of the pool increases in volume and force, water is forced out through the restricted opening at the top of plate 8, and a substantially surf-like wave produced. This movement, it should be noted, takes place entirely around the side of the pool as the movement of the pool progrosses.

Various modifications of minor details of the improvements disclosed herein doubtless readily will suggest themselves to those skilled in this art, but such modifications fall Within the scope of my inventive rights, and

my invention is not to be construed as being limited to any details not specifically set out in the claims.

Having now fully disclosed the invention, what I claim as new, and seek to secure by Letters Patent, is

1. In a bathing pool apparatus, a circular tank having a curvilinear side wall and having a central pivotal bearing beneath the tank, an inner perforate wall adjacent the 1 side Wall, and means .for imparting a circular tilting motion to the tank to eflect a throwing out of a spray of Water from be-' tween the walls.

2. Ina bathing pool apparatus, a circular tank having a curvilinear side wall and having a central pivotal bearing beneath the tank, aninner curvilinear perforate wall 'arranged adjacent the side Wall and closely spaced with respect thereto near the top, and means to effect a surge of water around the side wall to cause it to be thrown inwardly as a spray from between the inner and outer walls.

3. In a bathing pool apparatus, a circular tank having a curvilinear side wall and having a central pivotal bearing beneath the tank, an inner curvilinear perforate wall arranged adjacent the side wall and closely spaced with respect thereto near the top, and means for imparting a circular tilting motion to the tank to effect a surge of water against the side wall and cause it to be thrown inwardly as a spray from between the inner and outer walls.

In testimony whereof I allix my signature.
